Before Connecting
Before connecting other devices, connect the jack side of the
accessory power cable to the AC inlet of this unit.
Before connection is made, turn off the main power switch
of this unit and the power of all other connected devices to
prevent accidents due to noises generated unexpectedly.
How to connect power supply
Use the accessory power cable and insert the AC plug in an
outlet on the wall in the room where the unit will be installed.
How to connect output devices
1. Surely connect the output terminals of this unit to the line
input terminals of a control amplifier or an integrated am-
plifier using RCA pin-plug cables between the R-channel
and L-channel. If the grounding side of the pin-plug cables
is inadequately connected, noises including hum may be
generated, resulting in an adverse effect on the S/N ratio.
Therefore, insert the cables all the way.
2. Do not connect the output terminals of this unit to the
phono (PHONO) input terminal of a control amplifier or in-
tegrated amplifier. Failure to observe this may not only dis-
tort the phono amplifier signals of the integrated amplifier
or a control amplifier but also damage the amplifiers. Be
sure to connect the terminal to the line input terminal. Do
not insert the supplied short pin into the output terminal.
If the pin is inserted into the output terminal, no sound will
be generated.
3. Sound volume adjustment shall be performed by the con-
nected control amplifier or integrated amplifier because
this unit has no sound volume adjustment function. Sound
volume shall be set to the minimum when this unit is being
connected. If sound volume is set to a high level at pow-
er-on, sudden loud sound may be generated, which may
cause hearing loss or damage to the speakers.
Please be advised that the sound volume shall be set to a
low level at first and adjusted according to your taste after
the sound comes out of the speakers.
Cartridge connection
1. Insert the pin-plugs of an RCA pin-plug cables from an
analog player or a tone arm with a cartridge mounted into
the input terminals of this unit. At this moment, be sure
to make a connection without a mistake between the
R-channel and L-channel. If the grounding side of the pin-
plug cables is inadequately connected, noises including
hum may be generated, resulting in an adverse effect on
the S/N ratio.
2. Grounding between analog players or tone arms and this
unit is needed. Be sure to connect the ground wires that
come from tone arms in parallel with pin-plug cables to the
ground terminals of this unit.
If the ground wires are inadequately connected, noises
including hum may be generated, resulting in an adverse
effect on the S/N ratio.
3. To listen to music with the analog player connected to the
input terminal 1, 2, or 3 and cartridge, select the connect-
ed input terminal with the input selection switch.
Do not connect the output of an analog player with phono
equalizer embedded to this unit. Failure to observe this
may not only distort the amplifier signals but also cause
a malfunction.
Connect the output of an analog player with phono equal-
izer embedded to the line input of an integrated amplifier
or a control amplifier.
